There are various methods and tools you can use to test SEO tactics, depending on your goals, resources, and preferences. A/B testing, for instance, involves creating two or more versions of a web page or element and showing them to different segments of your audience. Then, you measure which version performs better according to your metrics. This can be useful for testing changes in design, content, layout, or features that can affect user behavior and conversions. Split testing is another option which entails creating two or more versions of a web page and showing them to different subsets of your traffic. This method is ideal for testing changes in title tags, meta descriptions, URLs, or canonical tags that can affect SEO performance and visibility. Lastly, multivariate testing requires creating multiple combinations of different elements on a web page and showing them to different segments of your audience. This method is great for testing multiple changes in design, content, layout, or features that can affect user behavior and conversions. Google Optimize, Optimizely, VWO, Google Search Console, RankScience, and DistilledODN are some tools that can help you run these tests.
